I suspect you haven't configured your document's toclevels. For example, Spring Boot's documentation uses :toclevels: 4 with this backend and shows four levels in the table of contents.

thank you very much ; up ssue has been resolved ; another question , how to set up html "shortcut icon" and change spring icon ; 非常感谢您如此快速的回复，上面的问题已经解决。另外的问题： 如何设置html tab 图标，以及更改spring 图标；

The purpose of this project is to produce Spring-branded documentation. If you want to use it for another purpose then you are, of course, free to modify it to meet your needs but such usage isn't something that we intend to support or that we can afford spend time on.
